The Nine Ninja Hand Signs of the Kuji-in

Stealth, guile, cunning and death; this is the way of the ninja. Bound by codes and forged in the ancient traditions of the East, the ninja warrior has adopted and perfected techniques from the far distant past, honing them for his own particular needs. The Kuji-in hand signs are certainly no exception. Developed by Taoist and Buddhist practitioners, these potent gestures now serve far darker masters. The nine ninja hand signs of the Kuji-in form the powerbase of the deadly shinobi warrior.


Ninja Rin – The Diamond Thunderbolt

rin-ninja-handThe seal of the diamond thunderbolt inspires both physical and mental strength. It is a pre-action hand sign, channeling power throughout the body in preparation for combat. The buildup of Rin energy often causes a release of bodily gases, a side effect known as “The Stench of Death” within the ninja community.

Ninja Pyō – The Great Thunderbolt

Pyō, or the seal of the great thunderbolt, enables a ninja to direct his energy. When fully charged, the ninja can quite easily crush a child’s skull with one hand or rip the beating heart from an adult panda. The seal of Pyō is a particularly complex one. Trainee ninjas are often beheaded in battle while trying to figure out the correct finger position.

Ninja Tō – The Outer Lion

Despite being seen by many ninjas as “a bit gay”, Tō is nonetheless a powerful symbol. The seal of the outer lion helps a ninja to achieve a sense of harmony. At a meditative level, this sense of harmony is calming, connecting man with his environment. Hardcore ninjas push Tō to logical extremes. Total harmony with the universe reveals the insignificance of all life, turning the ninja into a completely cold, perfectly harmonized killer.

Ninja Sha – The Inner Lion

sha-ninja-sealEven ninjas suffer occasional cuts and bruises. The gesture of Sha promotes the healing of both the self and others, a bit like having Dr. House as a spirit guide.

Ninja Kai – The Outer Bonds

kuji-kai-ninja-hand-sealKai enhances a ninja’s premonition of danger. This enhanced sensory awareness also gives an insight into the general emotional state of others, making ninjas highly effective card players. A 2001 study by the Institute of Martial Arts and Brawling found that 38 percent of a ninja’s yearly income comes from poker tournaments (not online). Many casinos have since implemented restrictions that limit ninjas to slot machines and roulette.

Ninja Jin – The Inner Bonds

jin-ninja-hand-signJin allows a ninja to hear the thoughts of others, much like Mel Gibson in What Women Want. The seal of the inner bonds also shields a ninja’s thoughts from others. Jin is a high-level ability, and a potentially dangerous one. If performed incorrectly, the ninja will shield his own thoughts from himself, plunging him into a vegetative state from which there is no escape. Senior ninjas jokingly call this “Fuckuji-in Up”.

Ninja Retsu – The Wisdom Fist

retsu-ninja-handsRetsu is the seal of the wisdom fist, also known as Chiken-in (not to be confused with the Chicken Inn in Chicago, known for its excellent chicken and courteous service). The implications of this particular Kuji-in are profound. In theory, Retsu gives a ninja control over time and space. However, a May 2007 survey found that 9 out of 10 ninjas believed that controlling space-time, while cool in theory, was really “a load of glorified, mystical bullshit”.

Ninja Zai – The Ring of the Sun

zai-ninja-hand-sealThe seal of the ring of the sun gives a ninja limited elemental control. By connecting the ninja with nature, Zai allows the warrior to use the sky, the river and other natural elements in battle. At the lowest level of control, a ninja can influence poultry and rodents, forcing them into frenzied attacks against enemy warriors and strongholds. The mightiest ninjas are able to control larger beasts such as yaks, camels and elephants. On January 16, 1999, shinobi master Yamashiro Toshtoshitora controlled rock legend Meat Loaf for a full 16 minutes during the filming of Fight Club.

Ninja Zen – The Hidden Form

kuji-in-zen-ninja-invisibilityZen offers far more than the self-exploration and enlightenment typically sought by aging hippies and cross-legged, yoga obsessed MILFs. For the ninja, the seal of the hidden form offers the ultimate stealth weapon: invisibility. In the entire history of ninjutsu, only eight ninjas have ever been credited with full invisibility. Of those eight, six were never seen again. Witnesses saw the two remaining ninjas vanish and reappear during the legendary sake binge of 1333. Records taken during the 49-hour event also list 68 deaths, 16 marriages, 11 pregnancies, and the appearance of 4 levitating rabbits, an eight-armed giant and a laughing wall of fire.

      There is no easy answer to that, Shun. The way of the Ninja is a dark path, and one that requires a life of dedication. Before entering such a world, you must have mastered many forms of combat, both ancient and modern. If you feel you are ready, you must find a Master to oversee your training. Only you, however, can seek out such a man — or wait for him to find you.

        The way of the the Ninja is only a dark path if you want to be a dark ninja. If you don’t want to be a dark ninja, then the path is light, life becomes peaceful, and is often beautiful. Be careful about learning the combat techniques; if you don’t also study the philosophy and develop an awareness of when/where to use the techniques, they will not work, and you will only end up hurting yourself, others, and discrediting the art.

          Yes. Subtlety is so important. In training, slow is fast, soft is hard. The mind is a beautiful animal let loose in heaven. Paradoxically, the old weak teachers have the most experience and knowledge to give. Insight and self knowledge. In time we evolve as like chinese medicine is evolving. This path has dignity.

          Sifu Stephen K Hayes of Germantown, Ohio, or his Master Dr. Masaaki Hatsumi from Togakure Ryu Ninjutsu in Iga province Japan are your best bet….also Jack Hoban, and Bud Malmstrom, both taught by Sifu Hayes…… Sifu Hayes, and Dr Hatsumi are both on Facebook

        Mastering or at least familiarity with old and new forms of combat are close to the core. Closer still, is the ideal of harmony with the Earth and the Spirit. Tolerance, love. Younger students are almost always better than older students, so start quickly, life is short. The training is everywhere, all around you.

        They way of ninjutsu is not dark, but harmonious. If the practitioner has dark intents, then dark things will be the results of his practice. To the dark practitioner there will always be a balance. Those who seek the path pray you all good luck, and that you fully grasp the understanding of the powers you seek. I hope you use them for the overall good of this world because there is way to much negativity. Take care. Osu!

    I am old and orthodox about training, and have a gripe about the way the hand mudras are portrayed here, and the ads, but nevertheless, humor.

    How you move, how you touch, how you think; 3 to 4 years of dedicated training. The herbs and massage protocols of medicine for injury and maintenance. The use, familiarity and maintenance of traditional and personal weapons, which evolve. But always, the discrimination between a conflict and an opportunity for reconciliation.

    We are the honey bees that search the earth for knowledge and advantage and love. Whether its the CIA black book of improvised weaponry, or old rin stances of supremacy, or diplomacy. Survival of self is only part.

    I would like to train to be a ninja if possible, i tried to train myself with meditation using the kuji-in. It provided me the power to control my mind but specifically respect within myself. How will I be one with nature? I also joined wushu before then I trained myself with the basic weapon like kunai but i use a dagger and i throw them directly to the tree. How do jump high like a ninja? does it still have something to do with the martial arts training like tony jaa? or have something to do with the kuji-in? im really interested. Im from philippines.

    U have to do 100 pushups to be wealthy to be a ninja. Then do a meditation for 30 minutes. Learn ur jutsus e.g. Kenjutsu,genjutsu,taijutsu, kinjutsu and shinobi jutsu. Learn to swim silently, climb trees faster, learn to be stealthy. learn to use a kusarigama, a ninjato, a bo staff, nunchuks, a shuriken an etc. Learn to do a split, a flip and learn to blend in colour. learn to be sneaky. Always keep in mind that the samurai is the enemy. I am a koga ryu 5 kyu ninja

      To be a Shinobi warrior takes more than physical strength and combat. By the way you spell and write you are not ready to be a Shinobi warrior

          Are you certain that you are shinobi? Because I would think a true shinobi would have mastered observation, including the difference between the letter I and the number 1. I especially question your shinobi status when you make this mistake immediately after chastising another’s worthiness based on how they “spell and write.” Surely, reading comprehension is just as important.

    Your post on Ninja Zen is disturbing (1333) and distasteful. Why would the highest level Ninja kill 68 peoples for any reason? You make Ninja look like mad psychopaths. Thank you for the hand signals, but you are no Shinobi

    Over many moons I have become a true Shinobi warrior one of the few left in the world.
    It is a hard journey. The hand gestures are just symbols. Usually used as showing your level or your sensi.

  22. August 26, 2016 at 2:27 pm

    No offense to anyone but it also helps when your parents one or both are japaneese and also come from the Samuri era
    What she taught me I still use today why I have no fear in putting someone or thing down depends on how things transpire more training I don’t have the time for but like I said somethings will supprise you when you learn to medatate and see things before you the outcomes

    There is no source, the OP treats the subject like a joke, and no one seems to be bothered by it.
